What's New

The latest GMC Sierra 2500 doesn't see many changes this manufacturing year. However, the base model is now known as the Pro (previously, it was the Sierra).


The GMC Sierra 2500 is available in five trim levels, with the Denali being the most luxurious of those trims. The GMC Sierra 2500 can be outfitted as a truck with a regular crew cab or an extended cab. The bed lengths include a standard length, a short length, and a long length bed. Drivers should remember that some cab configurations can only be had with certain bed lengths. Drivers looking to add the multi-function tailgate should keep in mind that this option isn't available on the Pro or SLE models.


The Sierra 2500 offers a wealth of safety features, including trailering packages and driver assists. However, many are optional or only available on upper trim levels.


All GMC Sierra HD trucks have an eight-inch infotainment screen; Apple CarPlay and Android Auto are standard, as is a mobile hotspot. Upgrades include a larger touchscreen and built-in navigation.


The standard GMC Sierra 2500 is a 6.6-liter V8 gasoline engine that provides drivers up to 401 horsepower and an impressive pound-feet of torque. This engine comes paired with a six-speed automatic transmission, and drivers may opt for either rear-wheel or all-wheel drive. (Four-wheel drive is available, but it is usually an option for higher trim levels.)

The optional engine is the much-lauded Duramax diesel engine. This engine is also a 6.6-liter V8 engine. It offers horsepower of up to 445 and the torque measures at a whopping 910 pound-feet of performance power. This diesel gets paired with an Allison ten-speed automatic engine, and one may choose either rear-wheel or all-wheel drive. Those who regularly tow a great deal of weight will certainly appreciate the power of the Duramax powertrain.

Those who need not only power but the ability to capably go off-road will want to consider the AT4 trim, which comes outfitted as more of a truck that is just as capable of going off the beaten path as it is on the pavement.

The GMC Sierra 2500 is capable of towing up to 18,500 (when outfitted with the Duramax). The payload of the GMC Sierra 2500 HD is 3,979 pounds.
